Jan 19, 2017· copper mining and refining process offers 1746 alluvial gold mining process products About 89% of these are mineral separator, 1% are crusher, and 1% are mine mill A wide variety of alluvial gold mining process options are available to you.
The final product of the refining process is electrolytic tough pitch (ETP) copper normally containing between 9994 and 9996% Cu Cathodes are re-melted under controlled conditions and cast into forms suitable for further processing
Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below) The anodes for this process were traditionally lead-based alloys, but newer methods use titanium or stainless steel
The final step is a process called electrorefining This is done by electrolysis where the copper anodes from the smelter become positive electrodes and thin, three-foot square sheets of pure copper are used as negative electrod
